The eight trigrams
Earth Trigram: 坤 ☷
Study kun when you want to understand yielding strength, capacity, and the grounded field that receives and stabilizes change.
In short
Kun is the all-yin trigram. It represents receptivity, containment, support, and the ability to carry form.
Three-line structure
坤 is written as ☷ and encoded as 000. Read from bottom to top, its lines are bottom yin, middle yin, top yin.
This matters because the I Ching is structural first. The character of 坤 begins with its exact line order, not just its later symbolic associations.
What 坤 contributes to a hexagram
Kun is the all-yin trigram. It represents receptivity, containment, support, and the ability to carry form.
When 坤 appears as a lower or upper trigram, it changes how the full hexagram is read by contributing its own pressure, orientation, and rhythm.
How to study it well
A strong way to study 坤 is to learn its line pattern, its natural image (地), and then notice where it appears inside hexagrams.
That approach keeps the trigram readable as structure, symbol, and part of a larger figure all at once.
